Boas Pessoal eu tenho o seguinte código:
login.htm
<html>
<head>
</head>
<body>
<br>
<br>
<div align=center>
<h1>Login</h1>
</div>
<div valign="center" align=center>
<form action="loginin.php" method="post">
NICK:<br>
<input type="text" name="nick">
<br>
Password<br>
<input type="password" method="post">
<br><br>
<input type="submit" name="submit" value="submit">
</form>
</div>
</body>
</html>
e depois tenho esse para efectuar o login:
loginin.php
<?php
include "conecta.php";
echo "<br><br>";
$nick=$_POST['nick'];
$password=$_POST['password'];
$sql=mysql_query("select * from utilizadores where nick='$user' and password='$password'");
if(mysql_num_rows($sql)>0){
echo "user existe";
session_start();
$_SESSION[user]=$user;
header("location:www.topicos_recentes.php");
}
else{echo "user nao existe";}
?>
o que se passa é o seguinte, ele não consegue criar as sessões e dame sempre o seguinte erro:
"user existe
Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /home/www/bitzero.freehostia.com/forum2/loginin.php:3) in /home/www/bitzero.freehostia.com/forum2/loginin.php on line 9
